It is not false...
We just take the problem from a different end: you on the electric power side ... me on the physical side ...
I still have doubts about the 0.22 Ohm ...

Do some tests by taking a well salted water is rho = 1500 microS.cm and say 1m² of plate
R = rho * L / S
with rho = resistivity (in Ohm.m or Ohm.cm)
The space of the plates (m or cm)
S = area (m² or cm²)
L = R * S / rho = 0.22 * 10 000 / 667 = 3.3 cm
Ah well I said nothing with 1m² and well salted water it is within the limit of the possible!

At a temperature of 20 ºC:
Pure water has a resistivity of around 25 MOhm.cm, (0,04 microS.cm-1)
The water obtained by demineralization commonly has a resistivity of 18 MOhm.cm (water necessary for the manufacture of integrated circuits), (0,06
The drinking water of the urban distribution network has a resistivity of the order of 1000 to 5000 MOhm.cm (200 to 1000 microS.cm-1): 90% of the withdrawals served in France.
Notes: The resistivity of drinking water is subject to variations like all its other characteristics: the range proposed is only indicative.
Decree 89-3 on water intended for human consumption (EDCH), does not indicate a limit of conductivity, however the maximum salinity limit is 1,5 gL-1 (dry residue at 180ºC), this which corresponds approximately to a conductivity of 2000 microS.cm-1.
The Guide Level of the EWC directive indicates: 400 microS.cm-1.
Furthermore, it is considered that water with a conductivity greater than 1500 microS.cm-1 is difficult to use for irrigation needs (salinization of the soils which make them unsuitable for cultivation).

AAAHHH! you become reasonable
interresting formulation:
a priori, a normally mineralized water with a conductivity between 2000 and 4000 Ohms / cm, a pure water is greater than 30 000 Ohms / cm, a little acid can easily lower the conductivity to 500 Ohms / cm.
which becomes with stainless steel plates of 25x25cm
L = R * S / rho = 0.22x625 / 500 = 0.27 cm COOL! I was considering 3mm

where are the 667 ohms / cm coming from?R = rho * L / S

It is the reverse of 1500 microS.cm

Yes except that adding products your water will cost you more than what you want ...
